to which it appertains to make and use the same, reference being had tothe accompanying drawings, and to letters or figures of reference markedthereon, which form a part of this specification.

This invention relates to improvements in hinges for doors, windows,flaps and the like, adapted to be used at the same time as locks andadmlttmg a swinging of the door, window or the like along either of itsopposite vertical edges. In the hinge according to this invention thegroup of members .provided in connection with the hinges hithertoproposed for locking the sections of the latter and comprising meansadapted to be moved relatively to the sections of the hinges areavoided, so that the design of the hi age can be considerablysimplified.

The hinge according to this invention comprises also means adapted tolock the movable part of the door, window, flap or the like, 2'. e. theleaf of the door or of the flap or the window-sash, to the stationaryframe.

- This invention will now be more particularly described with referenceto the accompanying drawings illustrating by way of example severalconstructions of carrying out the invention. In these drawings:

Figure 1 is a side view of a strapor platehinge according to thisinvention;

Fig. 2 is a cross-section on the line II-II of Fig. 1;

Fig. 3 is a top view of the lower section and Fig. 1 a bottom view ofthe upper section of this strap-hinge.

Figs. 5-8 illustrate a ing to this invention,

Fig. 5 showing this hinge in the closed position and some portions of itin section;

Fig. 6 is a section on the line VI-VI of butt-hinge accord- Figh is atop view of Fig. 5,. the section of the hinge fixed to the movable leafor sash being however omitted.

Fig. 8 illustrates the upper portion of a door to which the butt-hingeshown in Figs. 5-7 is fitted.

Figs. 9 and 10 show amodified construction of a butt-hinge, and

Figs. 11-13 show a further construction of such. a butt-hinge,

Fig. 11 being a cross-section, whereby the section fixed to the leaf ofthe door is omitted, and

Fig. 12 illustrating a front view of a portion of the hinge shown inFig. 11.

Fig. 13 shows a similar section as Fig. 11, the section fixed to theleaf'of the door being also shown in this figure.

Referring at first to Figs. 1-4 of the drawing. 1 denotes a section of astrapor platehinge provided on 1ts bottom side with an annular flange 2.The latter has an internal thread. 3 denotes a sleeve screwed into theflange 2. In the sleeve 3 is'mounted a pin 4: having a tapering upperend. This pin 4 has a cylindrical portion having 'a working fit with theinner wall of the sleeve 3 and it is rigidly connected to a shaft 5 ofsmaller diameter. The lower portion of the latter has a working fit in ahole G'provided' in the lower end portion of the sleeve 3. A helicalspring 7 surrounding the shaft 5 presses the pin 4 into a hole providedin the section 1 of the hinge; the greatest portion of the pin 4projects beyond said section 1.

3 denotes a second section of the strapor plate-hinge having ataperlng'recess 9. 10 denotes a groove of circular shape, the axis ofwhich coincides with that of the recess 9. The groove 10 communicateswith a lateral slot 11 arranged substantially at right angles to thelongitudinal axis of the section 8. A projection 12 of the section 1 ofthe hinge is adapted to fit into the groove 10.

The section of the strapor plate-hinge just described is provided inorder that it may be so fixed to the frame of a door, window, flap orthe like that the axis of the pin 4 coincides with the line in whichlies the pivot axis of the door, window or the like. The section 8 ofthe hinge is adapted to be fixed in a like manner to the leaf of a dooror flap or to a window-sash. Similar strapor plate-hinges are fitted inthe same manner to the three remaining corners of the door,- window orflap or the like and to the frame of said door, window orflaprespectively, so that a second pivot axis is provided besides that onealready. mentioned. In consequence of this arrangement,'the door,window, "flap or the like can be swung. either to the right or to theleft, as desire Let it be assumed for instance, that the described'strapor plate-hinge has been fitted to a door and that theleafof'the-latter is I just in the closed position. In this position :oflith leaf, the parts of the hinge assume relatively to each other theposition shown in Figsiland 2, 2'. e. the pin'l projects intoith'erIrec'eSs'Q-of the section 8. The projection l-'5 12 engages intothe groove 10 and itassumes -such a:position relatwely to the slot 11that a portion of it extends into an'end portion 10 'ofitheigroove 110which is not concentric to the recess 9, the greaterrpart of :said pro-2o je'ctio'n 12"-being"then situated between the -recess'llandr-a'portion of theiner wall of the groove 10, while a smallportion'ofiit'lies -behind the tonguet shaped member 10 of the plate'8..Thus, it will'be evident, that 25 thefrleaf'ofthe'door is not only heldinthe locked position by the pins 4, but-is also prevented from fallingout of the frame owingito the" fact thatFthe projection "12 "ex tendsipa-rtly into :the portion 10 ofrthe ggroove 'l0."Whenythedoordssoopened that ithez hingeiillus'trated in Figs. 1-4 rlies in the. ipi vot a'xis' of the-door, the leaf of'ithe latter :hastoi be moved "at 1 first in 'thedirection of the-' arrow (Fig. 4c)'untilith'e "recess 11 of 315 iheeoppositexhinge (which is not r shownon the drawing) gli'es-wholly'opposite the pro- Ejection 1 2' of thiShinge, so that "the "section 8 iof the latter fic'an be uncoupled-whilethe @111 4i-is forced I back and r theproj ection 12 is Moved into the:slot': or recess-11 and out of the groove 'lO from the section 1 ofthis hin ge. "Whilefthe leafof the=do0r is moved in the direction justreferred to, the section 8 of the hinge illustrated in Figs. 1-4 is 45shifted in su ch a direction-that the proj ection 12 of this hinge is"forced into X the portion 1 0 of the groove 10. Owing to: this, thesection 8of the hinge acting as pivotis coupled to ;the section 1 ofthis "hinge by the 5 0' projection "12 even when the lea'f'of the dooris moved outofits closed-position. After the"'sectionsof thehinge whichis not: shown on the drawing have been uncoupled, *the P1114 of'thehinge'sh'oWn' in jFigs. 1-4 is again forced wholly into the recess9aupon a ft'lrthe'r openin'g 'of the leaf of thei door, the. groove '910of E the section 8 cooperating then with the proj ec'tion 12, wherebythe lat ter 'locks the section *Sto the" section 1 of this hinge.

' *Whe'mit is intended to transfer the "pivot axis-of the leaf of thedoor into {the hinge lying- OppOSi'te that one shown on the 'd-ra'w-'lng, ithe leaf of the door is moved at first 5 t *gether with thesection 8 of the hinge illustrated in Figs. .1-4 in the direction of thearrow 1 1 (Fig. 4), so that the slot 11 comes to lie wholly oppositethe. projection 12 and the section 8'c'an be'un'coupled from the sec,tion 1 in the directionof the arrow 15 (Fig.

4), i. e. in the sense in which the leaf of the door is opened. In orderthatthepin 4 does not have'to overcome a too great resistance when thedoor is shut, a recess 16 is provided in the section 8 in proximity ofthe recess 11.

In the secondembodimentof the invention "illustrated in Figs. 58andhaving the form of a butt-hinge, l7 [denotes a cylindrical :memberprovided at itstwo: ends with'conr cal recesses 18. "Said-member17 ismount edtin aplate 20, one endof which isso bentas to forma knuckle 19.This plate isfor se curing the butt-hinge to afiap or alea'f, for1nstance:to the sash ofa window,'or, :as

shownin Fig. 8, to theleaf of a door a. '21 denotes projections provided,on the cylindrical member :17 andwhich are I forlockin'g the leaf-ofthe door.

. The other section of the butthinge comprises two cylindrical sleeves22 mountedin knuckles 23. The latter ifo'rm: aportion'of a plate 24 bentto a cylindrical shape; The

plate 24 is 'for securing said second section of the butt-hinge'totheframe of a flap or leaf of a door. .In F ig.-8'the plate"24.is fixedfor instance to the frame so of the door. The

'sleeves22 are held stationary in the knuckles 23 'by means of screwthreaded heads 25. In

:each sleeve. 22 is mounted aI'lpin 26 having. a

tapering end ipassing through the t'apering aperture 27 'of an. end wallof the 1 sleeve '22. The pin =26"has an integral shank "2'8 guided inthe screw threa'de d headu2'5. 29"d eH0l18Sl2l helical springadapted'toipress theztapering head :of the pin "26 into the aaperture 27. Eachsleeve 22 is provided 'atnthatof'its ends-arranged adjacent rthe: part20, with a head 1 having a groove "30 lying outside the circumference ofthe sleeve22 and having.

the shape of a semi-circular segment, fathe ends of whichllie in arlineparallel to the end of the groove 3O which is smaller than the Width ofthe projection21.

Upon aunovement of :thesection of'the butt-hinge fixed to theleafwtowarrhthe sec tion of the butt 'whinge fixed'gto th'eiframe, a.when itheileaf is shut; the cylindrical part 17 is movecl into thespaceprovided between the sleeves 22, the resiliently mounted;pins' 26 beingfthe'rebyr pressed 1 some-what apart and effecting a coupling of the twosections of the butt hinge as soon as they are caused to engage theconical recesses 18. When the cylindrical part 17 is moved into thespace provided between the sleeves 22, the projections 21 are forcedinto that portion of the grooves 30 which is confined at one side by thetongues 31, the resilient end of the latter being thereby moved slightlyaway from the sleeves 22.

When this butt-hinge has to act as a pivot for the leaf of a door, or ofthe sash of a window or the like to be opened or closed,-

the tongues 31 press the projections 21 into the grooves 30, 2'. 6. theyprevent the projections 21 from being moved against the end wall of theportions of the sleeves 22 in which the grooves 30 are provided. Thesections of the butt-hinge are consequently prevented from beinguncoupled. The tongues 31 constitute in this embodiment of the inventionthe means preventing an accidental or automatic uncoupling of thesections of the butt-hinge and they provide for the proper passage ofthe projections 21 into the grooves 30. When the projections 21 havebeen moved into the grooves 30, any uncoupling of the sections of thebutt-hinge is no longer possible, as theprojections 21 are then lockedin the grooves 30.

In order to facilitate the moving apart of the pins 26 when the sectionsof the butthinge are coupled together the end forces of the section ofthe butt-hinge of which the cylindrical member 17 forms a part, areprovided with recesses 32.

The third embodiment of the invention illustrated in Figs. 9 and 10,which figures show also a butt-hinge, comprises also a resilient tongue31. The free end 31 of this tongue is parallel to the circumference ofthe sleeve 22. When the parts of this butthinge are fitted together, theprojection 21 forces the free end 31 of the tongue 31 slightly outwardand a portion of it is then moved, as shown in Fig. 10, behind said end31. When the sections of the butt-hinge are moved relatively to oneanother, the tongue 31 presses the projection 21 against the sleeve 22until said projection 21 has been moved into the groove 30. Thisconstruction is particularly adapted to be fitted to lighter flaps andleaves, for instance to light doors.

In the fourth construction according to this invention illustrated inFigs. 11-13, the tongue 31" is formed integral with the sleeve 22, itbeing thus rigidly connected to the latter. This tongue 31" has in thesame manner as the tongue 31 shown in Figs. 9 and 10 an end 31 parallelto the circumference of the sleeve 22 behind which is moved a portion ofthe projection 21 when the leaf of the door or the sash of the window;to which the hinge is fitted, is shut.

When the butt-hinge illustrated in Figs. 11-13 has to act as a pivot forthe leaf to be opened, the latter is moved at first to a small amount inthe direction of the arrow 33 (Fig. 13), so that the projection 21 ofthe opposite butt-hinge not shown on the drawing is able to move infront of the end 31 of the tongue 31.. As said movement of the leafcauses a small relative rotary movement between the sections of thebutthinge that is just acting as a pivot, while no play is presentbetween the end 31 of the tongu 31 provided on said butt-hinge and theprojection 21, a. notch 34: is provided in the sleeve 22 so that theprojection 21 is able to assume an inclined position relatively to thesleeve 22 when the leaf is moved in the direction above referred to.When the projection 21 on the opposite butt-hinge has been moved pastthe end 31 of the tongue 31", the conical heads of the pins 26 of thebutt-hinge acting momentarily as pivot efiect a centering of thesections of this butt-hinge relatively to one another, the projection21, which has prevented until now an uncoupling of the sections of thebutt-hinge owing to its cooperation with th tongue 31", being then movedinto the groove 30.
